Annuals, seeds in the open border, in March and April ; 

 herbaceous perennials, also by seeds, as for annuals, 

 and division of the roots ; tender annuals require the 

 assistance of a hotbed before transplanting in May ;

 glass, and grown in fibrous loam, with a little peat ; 

 several of them, such as adpre'ssum, which sends out very 

 long shoots, should be tried against a wall. The fruit 

 of several, such as iata'ricum and Fagopy'rum, are used 

 for tarts.
